Starter Issue (will not turn over when hot)
I think I was told in the past that its heat from the exhaust messing with the starter motor but I don't remember what the resolution was.
390 with AT.
Basically the starter works fine when cold but when the truck is all warmed up it barley turns the motor over, or it doesn't at all.
Replace the starter?

I should add, if the engine is stock make sure the timing isn't set more than about 12-14 degrees.
Otherwise a stock starter on a built engine can easily handle 18 degrees initial. I had the same stock starter for the last 19+ years.

Well I don't think the motor has been built or anything. It has a stock 4 barrel intake so maybe the motor has some higher HP than what I used to have in the 2 barrel 390s have had in the past.
Don't know if I can afford the HP mini starters as I'm unemployed.

Snag a starter from the junkyard. Yours is toast. The early Ford starters can take a lot of heat before they go South. So if it is indeed nt wanting to work when hot, you have:
A) A bad starter
B) Weak cables
C) Over advanced initial timing

I run a 76 with a 360/390 and decided to start off with new headers and a 3" dual exhaust.
To date I have replaced 6 NEW starters all purchased from car quest at a price of $125.00. Granted I only paid that 3 times, since the last threee failures happened within the covered warranty time. Wrapping your starter and your headers (If you have them) Is only a temporary fix I finally decided. Call Summit or Jegs and dish out the $295.00 for a high torque mini starter, and don't forget to wrap it. I know it is crazy to pay that for a non race car application, but the time, frustration, and grief of changing starters will be well worth it my friend.

I think I would seriously have a look at the timing before I started buying $300 starters..............classic symptom of having timing too far advanced.........

I bought a nice Powermaster High Torque mini starter off ebay brand new for $150 or so compared to the $250-300. But, I'd actually just get a starter heat shield that wraps around the stock starter and go from there. Sounds like the starter is suffering from heat soak.

Not always so with heat soak. Before I had my timing right she would start fine cold. After the first run she would start hard. By that I mean start run for a min shut down then bam hard start. Never had a chance to get hot. Also my headers are no where near my starter. I have a 4 inch clearance around my starter. You more than likely need to retard your timing.

Has the timing been checked? Also, are you running headers that are close to the starter? Usually headers running close to starters will cause the heat soak symptom, but if the exhaust isn't that close than definitely the timing could be an issue. I also had that symptom too with timing.

Starter is old, tired and weak.
A healthy stock Ford starter will turn over an 11:1 427 with headers, or 10:5 428 or 10:1 390 and 14-18 degree initial timing in 100 degree heat after being ran all day.
And I have no true idea how old my starter was, been with the truck since 93 so who knows how long before that.
If someone is burning thru starters on a regular basis there are other areas that need attention like cables, solenoids, teeth condition etc. Stock Ford starters, Mopars too are darn tough and like anything Chevy's idea of a starter.

A brand new starter I'm assuming and not a crappy reman one.
